- Brief Summary
The COVID-19 pandemic has led to a mis/disinformation ecosystem that promotes divergent views of vaccine efficacy, as well as the legitimacy of science and medicine. Individuals are confronted with vaccine-related information from a multitude of sources, posing a challenge to identifying inaccurate information. COVID-19 vaccine uptake is lower among people with anxiety and depression than in the general population, due in part to higher levels of vaccine hesitancy. The prevalence of anxiety and depressive symptoms among US adults increased significantly during the COVID pandemic and has remained elevated. Interventions capable of mitigating the impact of vaccine hesitancy and mis/disinformation among undervaccinated people with anxiety or depression are therefore an urgent priority. Emerging evidence suggests that reasons for vaccine hesitancy and the impact of conventional vaccination messaging differ between those with and without mental health symptoms. There may also be added challenges overcoming logistical barriers to vaccination for people with anxiety or depressive symptoms.
The investigators aim to determine the effectiveness of two different brief digital intervention strategies compared with conventional public health messaging for increasing vaccine uptake in undervaccinated adults with and without anxiety or depressive symptoms. Attitudinal inoculation is a brief, scalable strategy that leverages the power of narrative, values, and emotion to strengthen resistance to mis/disinformation and reduce hesitancy. Though this approach has been shown to decrease COVID-19 vaccine hesitancy among US adults, the extent to which this approach increases COVID-19 vaccination remains unknown. Cognitive-behavioral therapy (CBT) is an evidence-based intervention for anxiety and depression. However, the efficacy of incorporating CBT-informed messaging in a vaccine promotion intervention has not been tested. The investigators hypothesize that both attitudinal inoculation and CBT-style communication will be more effective than conventional public health messaging to increase COVID-19 vaccination. The investigators also hypothesize that the CBT-informed intervention will be more effective than the attitudinal inoculation intervention for increasing COVID-19 vaccination among participants with symptoms of anxiety or depression.
- Detailed Description
The project will recruit undervaccinated participants with and without symptoms of anxiety or depression from the CHASING COVID Cohort, a large and geographically diverse community-based US cohort, to tailor and test the effectiveness of two brief digital interventions to increase vaccine uptake among adults with anxiety or depressive symptoms. The investigators will assign undervaccinated cohort participants, with and without symptoms of anxiety or depression, to: 1) an attitudinal inoculation intervention; 2), a CBT-informed intervention; or 3) a conventional public health messaging intervention without attitudinal inoculation or CBT-informed content. The investigators will examine the outcome of COVID-19 vaccination at 4 weeks post-intervention, conducting intent-to-treat comparisons between arms.

- Arm && Interventions
Group Intervention Description Attitudinal inoculation intervention Attitudinal inoculation Participants randomized to this arm will view a brief video addressing one anti-vaccine "meta-narrative" or issue (e.g., concerns about the vaccine not working) most salient to the entire CHASING COVID study population (per recent historical data) and focused on bolstering resistance to mis/disinformation. Cognitive behavioral therapy-informed intervention Cognitive-behavioral therapy-informed intervention Participants randomized to this arm will view a brief video using a CBT-informed approach and focused on addressing barriers to vaccination, with no inoculation messaging. Conventional public health messaging Conventional public health messaging Participants randomized to this arm will view a brief video conveying conventional public health messaging adapted from a review of public health public service announcements, with no inoculation or CBT-informed messaging.
- Primary Outcome Measures
Name Time Method Self-reported receipt of COVID vaccine dose by 4 weeks post-intervention 4 weeks post-intervention Following our theoretical premise that our intervention will impact the uptake of COVID-19 vaccination, the investigators define our primary outcome as self-reported receipt of a COVID vaccine dose in the 4 weeks post-intervention. Risk ratios will be used to estimate and compare the proportion of participants in each arm who achieved the outcome. The investigators will adjust for differences in measured pre-baseline variables to address potential imbalances and conduct a mediation analysis to better understand the intervention's mechanisms of action.
- Secondary Outcome Measures
Name Time Method Self-reported receipt of a COVID vaccine dose by 6 months post-intervention 6 months post-intervention The investigators define our outcome as self-reported receipt of a COVID vaccine dose in the 6 months post-intervention. Risk ratios will be used to estimate and compare the proportion of participants in each arm who achieved the outcome. The investigators will adjust for differences in measured pre-baseline variables to address potential imbalances and conduct a mediation analysis to attempt to better understand the intervention's mechanisms of action.
Vaccine hesitancy post-intervention immediately post-intervention, 4 weeks post-intervention, and 6 months post-intervention The investigators will estimate vaccine hesitancy at baseline, immediately post-intervention, 4 weeks post-intervention, and at 6 months post-intervention. People who indicate that they are "not willing" to get a vaccine dose will be defined as vaccine resistant, people who indicate that they are "somewhat willing" will be described as vaccine hesitant, and people who report that they are "very willing" or who report having received a vaccine dose will be classified as vaccine willing. Risk ratios will be used to estimate and compare the proportion of participants in each arm who are either vaccine resistant or vaccine hesitant to those who are vaccine willing at each time point. The investigators will adjust for differences in measured pre-baseline variables to address potential imbalances.
